This boolean data property marks components that serve secondary or supporting roles within causal relationships, indicating entities whose contributions are theoretically acknowledged but empirically modest or contextually dependent. When true, it identifies factors that provide background conditions, catalytic effects, or minor influences rather than primary causal forces. This property enables nuanced modelling of complex sociological phenomena by recognizing that not all participants in causal relationships operate with equal theoretical weight or practical significance. It supports more sophisticated causal analysis by explicitly documenting the hierarchical structure of sociological explanations and helping researchers focus analytical resources appropriately across different levels of causal importance.
